LEE DUKE, OF BOLLI'NG, ALABAMA.

ROSIN-HOLDER FOR VIOLINS.

Specification of Letters Patent.

. Patented Feb. 11, 1919;

Application filed February 5, 1918. Serial No. 215,533.

To all whom it may concern:

Be it known that I, LEE DUKE, a citizen of the United States, residing at Bolling, in the county of Butler and State of Alabama, have invented certain new and useful Im provements in Rosin-Holders for Violins, of which the following is a specification, ref erence being had therein to the accompanying drawings.

This invention relates to an attachment for string instruments and has for its principalobject the production of eiiicient means for rosining the bows for playing such instrument.

Another object of this invention is the production of simple and ethcient means for holding rosin upon the side of the body portion of string instrument so that the same will be in a convenient place so that the bow may be readily rosined.

A still further object of this invention is the production of simple and efiicient means which may be quickly attached to and de tached from the body portion of the string instrument.

With these and other objects in view this invention consists of eertain novel combinations and arrangements of parts, as will be hereinafter described and claimed.

In the accompanying drawings:

Figure l is a front elevation of the string instrument showing the rosining attachment applied.

Fig. 2 is a longitudinal section taken through the attachment.

Fig. 3 is a detail perspective view of the -shaped clamp used in connection with the attachment.

By referring to the accompanying drawings by numerals it will be seen that l designates the body of the string instrument which body portion is provided with recesses 2 on both sides.

Within the recesses are held the rosin 3 which is rotatably mounted upon a rod 4:; the rod 4; is provided at its ends with the knobs 5 and is fixedly attached to the U-shaped brackets or clamps 6. As is clearly seen by Copies strmg instrument which is of this patent may be obtained for five cents each, by addressing the Washington, D. G.

referring to Fig. 4., the U-shaped clamp is provided with threads. Through these threaded apertures 7 the bolt 8 is attached by screwing, so that the knob 9 which is made or covered with some soft material will be pressed against the sides of the recesses 2 thereby holding the rosin 3 in a desired position.

lVhen the bolt 8 is screwed sufficiently to hold the attachment in the desired position the lock nuts 10 are screwed upon the free end of the bolt thereby locking the whole device in the desired position. It should be understood that the rod 4: is forced through the apertures 11 and the knobs 5 are formed by flattening the end portions of the rod so that the rod 4 will be held in fiXed engagement with the U-shaped clamps 6 which are adapted to be formed of spring metal so that the same will give a little when the bolt 8 is screwed in tight engagement with the side portion of the recesses 2.

From the above description it will be seen that a very simple and eliicient device has been produced which may be attached to or detached from the body portion of any provided with a pocket similar to one shown in Fig. 1 and it will also be seen that the device is provided with U-shaped clamps which will allow the bolts to be tightened without injury to the woodwork of the instrument.

What is claimed is:

1. The combination with a violin provided with recess upon one side, of a rod provided with rosin thereon positioned in said recess, and means engaging the ends of said rod and detachably holding the same in said recess.

2. The combination with a violin provided with a recess, of U-shaped clamps positioned in said recess, rosin-carrying means mounted upon said brackets, and means engaging the walls of said recess and detachably securing said brackets therein.

In testimony whereof I hereunto aiilx my si ature.

gn LEE DUKE.
